What documents are required for the calibration of new project instruments (the first instrument calibration), namely individual calibration and joint calibration? What documents does Party A need to check? Does any expert know this? Could you give a detailed explanation? I searched online for a long time but couldn’t find it! ! ! ! Waiting online! Urgent, urgent, urgent. . . . . .
A factory certification and the factory calibration data sheet are sufficient
For example, in the case of flow meters, calibration is carried out using at least 5 points; the standard flow rates for these 5 points are provided, along with the flow rate of the meter being calibrated, the error amount, and whether it meets the required accuracy standards. That’s all. Do you have anything else?
It is estimated that what the original poster is asking about are qualification certificates related to personnel and equipment in a particular facility. According to relevant metrology regulations, those who are responsible for calibrating certain types of instruments must hold a \"calibrator certificate\" for those instruments; the standard devices used also need to have a certificate issued by the technical supervision authorities. Currently, there are more certificates available for personnel, while fewer exist for equipment (as long as the difference in grade between the main equipment and the standard instruments used is sufficient). It depends on the management practices of the company in question.
In the single-school approach, the verifier must hold a \"instrument calibrator\" certificate and have standard instruments as well as calibration certificates for those instruments; generally, only pressure-related instruments can be calibrated using this method, while no other types of instruments can.
The 4th floor is more or less the same; the debugging process mainly depends on the manufacturer’s requirements – **there are no strict rules**
